Description

Methods for beam-corresponding signaling, associated wireless devices and associated network nodes

This disclosure relates to the field of wireless communications. More specifically, the present disclosure relates to methods for beam-corresponding signaling, associated wireless devices, and associated network nodes.

Beam response is mandatory with capability signaling to indicate whether uplink beam sweeping is required. Currently, beam correspondence, BC, and signaling are defined for each wireless device (e.g., user equipment, UE) regardless of the antenna characteristics of the wireless device.

For example, a wireless device may have multiple antenna elements or antenna panels, leading to a variety of antenna features.

For example, the BC capability of a wireless device may depend on the worst antenna panel (e.g., the antenna panel with the worst performance) to ensure the reliability of the communication system. However, this may result in an unnecessary increase in uplink beam sweeping.

There is a need for further optimization of beam-corresponding signaling. Accordingly, there is a need for methods for beam-corresponding signaling that mitigate, alleviate or solve the above-mentioned drawbacks and provide improvement in beam-corresponding signaling by exploiting antenna features. For example, a wireless device may include multiple antenna panels and different antenna panels may actually have different capabilities for beam correspondence. Therefore, the present disclosure improves beam correspondence signaling by providing beam correspondence information per antenna panel.

This disclosure provides a method performed by a wireless device for beam-corresponding signaling. The wireless device includes a plurality of antenna panels including a first antenna panel. The method includes obtaining, for a first antenna panel, a first beam correspondence, BC, and capability parameter associated with a first panel identifier. The method includes transmitting a first BC capability indicator to a network node. The first BC capability indicator includes a first BC capability parameter and a first panel identifier.

Also provided is a wireless device, the wireless device comprising an interface module, a memory module, and a processing module, the wireless device configured to perform any of the methods described herein.

The present disclosure provides a method for beam correspondence signaling, performed by a network node, where the network node is configured to communicate with a wireless device via a wireless communication system. The method includes receiving a beam correspondence, a BC, and a capability indicator from the wireless device, wherein the BC capability indicator includes a BC capability parameter and a panel identifier, and the panel identifier is an antenna of a plurality of antenna panels of the wireless device. Configured to identify a panel, the BC capability parameter indicates a beam correspondence capability for the antenna panel identified by the panel identifier. The method includes determining, based on the BC capability indicator, whether per-panel beam corresponding signaling is supported by the wireless device.

Finally, a network node is provided, where the network node includes an interface module, a memory module, and a processing module, and the wireless device is configured to perform any of the methods described herein.

An advantage of the present disclosure is that the beam responsiveness is enriched by exploiting antenna features and providing beam responsiveness per antenna panel of the wireless device from the wireless device to the network node. The disclosed beam-corresponding signaling is advantageous in that it allows network nodes to make improved decisions about transmission strategies.

These and other features and advantages of the present disclosure will be readily understood by those skilled in the art by the following detailed description of exemplary embodiments of the present disclosure with reference to the accompanying drawings.

Various example embodiments and details are hereinafter described with reference to the drawings where relevant. It should be noted that the drawings may or may not be drawn to scale and that elements of similar structures and functions are indicated by like reference numerals throughout the drawings. It should also be noted that the drawings are merely intended to facilitate description of the embodiments. They are not intended as a limiting illustration of the invention or as a limitation on the scope of the invention. Additionally, the illustrated embodiment does not necessarily have all the aspects or advantages shown. An aspect or advantage described in conjunction with a particular embodiment is not necessarily limited to that embodiment and may be practiced in any other embodiments even if not so illustrated or explicitly stated.

The 3rd Generation Partnership Project, 3GPP, Systems, Beam Response is mandated to define signaling capabilities as follows: For example, a UE or wireless device that fulfills beam correspondence requirements without uplink beam sweeping will set the BC capability bit to 1. For example, a UE or wireless device that implements beam correspondence requirements with uplink beam sweeping will set the BC capability bit to 0.

Beam correspondence, BC, signaling is supported regardless of whether there are multiple panels within the wireless device; It is defined for each wireless device per frequency band. However, in real scenarios, different antenna panels within a wireless device may have different capabilities with respect to beam correspondence. Because there is no individually defined BC signaling per antenna panel, the BC capability of a wireless device may depend on the worst antenna panel (e.g., the antenna panel with the worst performance) to ensure the reliability of the communication system. Therefore, a network node can request uplink, UL, and beam sweeping since the BC capability is set based on the worst antenna panel. An increased number of wireless devices performing an uplink beam sweeping procedure is likely to result in increased uplink overhead and latency, and consumption of more network resources.

Additionally, for UL multiple input multiple output MIMO transmissions to multiple antenna panels, there may be a case where not all antenna panels may support BC with the selected BC capability setting.

The present disclosure proposes in one or more embodiments to indicate BC capability signaling per antenna panel instead of per UE, e.g. per antenna panel per frequency band. BC capability signaling disclosed herein includes information identifying a corresponding antenna panel within a wireless device (e.g., panel identifier).

A panel identifier as disclosed herein is referred to as an identifier that identifies an antenna panel and/or antenna subpanel. The panel identifier can be said to be a parameter that establishes the identification of an antenna panel among a plurality of antenna panels of a wireless device. A panel identifier may be used by a network node to identify antenna arrays, eg, a group of radiating elements.

The drawings are schematic and simplified for simplicity; they show only details essential to an understanding of the invention, and other details have been omitted. Throughout, the same reference numerals are used for like or corresponding parts.
